Facts: Polnado Warning

Out of 275 cattle breeds acknowledged worldwide, only 5-10 breeds are prominent in beef production.

Although cows have poor depth perception, they can see almost 360 degrees around them, and can distinguish between many colors.

On average, a U.S. dairy cow will yield more than 2,275 gallons of milk a year, or about 6.2 gallons a day.

There is only one species of domestic horse, but around 400 different breeds that specialize in everything from pulling wagons to racing.

Animal behaviorists have observed compulsive behaviors in domestic horses that feral horses do not exhibit; these include headshaking, weaving, stall-circling, striking or kicking the wall, as well as biting or kicking themselves. The researchers theorize that isolating these animals and keeping them in stalls has contributed to these behaviors.

Although they are much smaller, miniature horses should be vaccinated with the same dose size as standard-sized horses.

Sheep hooves contain two digits and grow like human fingernails. They should be trimmed every couple of months or so to maintain normal shape and structure.

Sheep can communicate emotions and messages based on the sounds, pitch and variance of their bleat; a young sheep can identify its mother by the sound of her bleat.

Livestock are dehorned to reduce the risk of injury to other animals and humans and to reduce the amount of space needed at feed troughs.

Like adolescent humans, male and female dogs mature at different rates; in larger breeds males may take a year longer to mature than females.

Dogs rely on their noses as their keenest sense; a dog's nose contains more than 220 million olfactory receptors. This is over 40 times as many as humans, who have just five million receptors.
